Filtering Mask with Math Pattern
This snazzy and smart Filtering Mask with Math Pattern looks great while keeping you covered! The outer layer is made of a tightly woven cotton that holds its shape. The inner layer is made of a soft brushed cotton layer. The inner layer has an overlapping slot that you can slip a PM2.5 filter into. The mask comes with two filter pieces.
You can wear this mask many times. After a week of wearing, remove the filter and replace it. Or you can wear it without a filter. Please check this document for information on how to put on and safely remove a face mask.
The PM2.5 filter reduces air pollution and airborne particulate inhalation, the cotton mask keeps your breath/sneeze/cough from reaching others. Perfect for daily use and outdoor activities.
